so me and my bf just had sex for the first time, we’ve been together for almost 2 months and we would have had sex earlier but he had to get surgery and his healing time was long, i haven’t had sex in a long time and just did with him yesterday. we did it a few times, he wouldn’t cum inside me but now my vagina stinks, it smells like a yeast infection but i know it’s not because i know what that feels like, but it’s grossing me out and i want it to go away. can anyone tell me what it is?
